Same problem as many "Warning (5) Dynamic Range Window violation"
I have been dealing with internet speed issues for about a year now. I was told my modem was bad replaced that, I was told it was a problem with the cabling in the house (not covered) I installed a new homerun to the termination outside, then it was I was maxing my bandwidth so I upgraded to gigabit, then the cable again (replaced again) now I am being told the modem is bad again. modems used: ARRIS SURFboard SBG6782-AC DOCSIS 3.0 Cable Modem and AC1750 Wi-Fi Router >Motorola 16x4 Cable Modem, Model MB7420, 686 Mbps DOCSIS 3.0 >NETGEAR Cable Modem CM600 Current setup: Modem:MOTOROLA MB8600 DOCSIS 3.1 Cable Modem Router: Netgear Nighthawk R7960PFirmware VersionV1.4.1.50_1.3.10 Any help is appreciated and welcome, anything other than its a bad modem or coax.

So I have a Arris SB8200, and it seems this kinda thing always happens this time of year. The drop line has been replaced twice in 3 years. Which leads me to believe it's something at the plant or not too far down the road as the configuration of our home network including the router and modem have been the same and have not moved since the tech installed and provisioned them. Doing this fixes it for a while and then it all goes out of whack, usually because the tech files a report to have a plant mechanic come out and look at everything and they fiddle with the node at the end of the street and that fixes it. When I see power levels this high https://imgur.com/a/9AYSJeF https://imgur.com/uLGfLLV And log files that look like this: https://imgur.com/E10yaYS It's kinda concerning that this is a repeat thing and that the logs are showing it's repeating over and over.4.1KViews0likes1Comment
